I tried many things some did work but for one or 2 times huge difference when fps work fine but then it came back the way it was, i believe its more of a hardware issue the its just a software! I have another iPhone 12 pro phone headphone stopped working took it to Apple to find out that the screen was not compatible with the phone!!!! I was like really!!! that was a new phone, everybody take your iPhone 12 to apple for compatibility test while its under warranty.
